A lower bound for the number of conjugacy classes of finite groups

Thomas Michael Keller

In 2000, L. Héthelyi and B. Külshammer proved that if is a prime number dividing the order of a finite solvable group , then has at least conjugacy classes…

Counting characters in linear group actions

Thomas Michael Keller

Let be a finite group and be a finite --module. We present upper bounds for the cardinalities of certain subsets of $\Irr(GV)$, such as the set of those $χ\in\Irr(GV)$ s…
